mobile mouth
A person who carries on cell phone conversations in public places in such a loud voice it's as if they're sure everyone just has to be interested in what they're saying.
Even though I was several aisles away in the supermarket, I couldn't help but hear that mobile mouth as clearly as if he were talking to me.

Getting oral pleasure(head) while driving down the road.
You want me to give you a mobile mouth hug while you drive me home?
